Good start

You need to make the textures work harder. Those pants should look like leather, with graininess and wrinkles and dust and not as reflective, instead of the pristine latex-look above. He's got a nice mouth and nose, but you copped out and didn't try the eyes. That would be okay, if you had more wild-looking, flying all over the place, hair with a finer texture. It is a good start, but there's room for improvement.

Also, use anti-aliasing to get rid of those horrible jagged lines (for example, between his gut and his belt).

rad

you should switch some more things up, like you did with the belt otherwise its very clearly symmetrically modeled
